So I just started playing morrowind about a month ago. Of course I am far from finishing it, and I have no idea where the story will go. I noticed that there a new addition to the GI hub. A wall that tells the story of the dragons. I am curious to read it, but I am afraid I will run into a major Morrowind spoiler if I do... I have already played Oblivion, so I am not concerned about that part of the story.. just Morrowind
Skyrim takes place 200 years after Morrowind/Oblivion. The only possible surprise is the very end, but it's actually not that hard to guess once you get your feet wet. I probably spoiled the game more for you right there than the GI website will.
